"Professor Hugo Strange"
The Batman arrives too late to stop a drive-by shooting. Before the man perishes, he mutters the words "fog" and "strange". Batman later learns that the victim was a former G-man and that he was referencing the notorious scientific criminal, Professor Hugo Strange.
Hugo Strange kidnaps electrical engineer Henry Jenkins, and forces him to design a device that will generate a perpetual fog wherever he requires it. With the fog in place, Strange's men can commit crimes with added stealth and evade police capture.
Batman eventually tracks Hugo Strange down and fights up against his men. He rescues Henry Jenkins and destroys the fog generator. Hugo Strange is captured and taken to jail.
